To take advantage of the best prices you will need to prove you are a leisure traveller, en route to heathrow airport, so you will need to give either yr flight details or yr holiday booking reference. I don't think you will need to give this when you arrive at the station but you may be asked to provide them on yr travels from the station to the airport.
Going to the airport by train is great, you can sleep, read a book (even at night), play travel scrabble, or just gaze out of the window... The other restriction to buying these cheap train tickets from the station to the airport is that there must be at least two adults travelling together. But another great advantage is that children go free. All children under five go free, and then one kidover 5 but under sixteen per grown up travelling on the train to heathrow airport.
make sure you leave plenty of time to get to the airport early enough to eat, shop and so on, so check the times of trains from northampton station before you go. If you have spare time at heathrow airport you can always read a book or play travel scrabble again! As you have bought your train ticket in advance, you don't need to fret about the opening hours of northampton station.
